The Helios Concept is a design study of a solar energy-powered off-road sporty vehicle. The body integrates a system of large photovoltaic panels that increases the energy charging capacity. It was designed by Kim Gu-Han from Universität Duisburg-Essen – Germany. The Helios is an electric off-road vehicle use powered by solar energy. To increase the surface area of the photovoltaic panels, when not in motion the upper surface of the car transform into a large “fan” with four wings to store more energy or to serve as an energy station. This transformable design was inspired by natural evolution – some animals have developed a stretchable skin to absorb more sunlight.
